RESUMO
PURPOSE: To study the current profile of secondary glaucoma in all age groups of patients presenting to a tertiary eye care hospital in Northern India Materials and methods: In this retrospective study, files of 5725 patients who were newly diagnosed to have glaucoma in our tertiary eye care centre from January 2014 to December 2016 were reviewed. Detailed data were collected from patient's records, including history, best-corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp biomicroscopy findings, gonioscopy, and fundus findings. Demographic data, aetiology, and management in all these patients were also noted. RESULTS: Out of 5820 patients who visited glaucoma outpatient department (OPD) in a tertiary eye care hospital during 1 January 2014 to 31 December 2016, 5725 patients were diagnosed to have glaucoma by the glaucoma specialists. Five thousand three hundred and six patients (92.68%) were diagnosed to have primary glaucoma and 419 patients (7.32%) were diagnosed to have secondary glaucoma. The leading causes of secondary glaucoma were found to be neovascular glaucoma (17.42%), trauma (14.80%), post-keratoplasty (13.60%), post-cataract surgery (13.13%), and lens-induced glaucoma (12.41%). Secondary glaucoma was found to be an important cause of visual morbidity with 71.17% eyes presenting with BCVA < 6/60, IOP > 30 mm Hg in 62% eyes and 72% with cup-to-disc ratio of ≥0.7:1. CONCLUSION: Secondary glaucoma is an important cause of visual morbidity. Timely diagnosis and prompt management are essential to prevent irreversible visual loss due to secondary glaucoma.
